Chapter 12. Network Reliability and Availability

12.1. Introduction

Chapter 9 described the network requirements of certain service classifications that can be offered over broadband FDM distribution networks. Among those are transmission quality, effective bandwidth, reliability (the probability that a system will survive without interruption for a defined period), outage rate (the average rate at which service interruptions occur), and availability (the percentage of time that service is available).
